A Great Western Mogul, built by a prolific engineer with five steam locomotives to his credit (not to mention the petrol-electric Class 15 currently listed).
An older engine, it has not been used in some years. Now requiring a thorough overhaul, the paintwork is dreadful, it needs new superheaters, the rods need rebushing and just about every gland that can leak does. Having said that, I think there is the potential to make a decent example of this good-looking thoough rarely modelled engine.
There's a clip of it running in the workshop yesterday here.
Complete with a set of drawings.
Locomotive 37 inches
Tender 24 inches
